Infrared sauna as exercise-mimetic? Physiological responses to infrared sauna vs exercise in healthy women: A randomized controlled crossover trial

Abstract

Background: Passive heat therapies have been reported to have similar effects on the cardiovascular system as exercise. Studies supporting these findings in healthy populations have predominantly been done with men using warm water immersions or traditional saunas, rather than newer infrared-based saunas. Objective: To explore short-term thermal and cardiovascular responses in women using an infrared sauna as compared to moderate-intensity exercise. Study design: Randomized controlled crossover trial with balanced allocations. Setting: Brisbane, Australia (August 2019 - March 2020) Participants: Ten healthy women (36 ± 9 years) Interventions: 45 min of resting, infrared sauna or indoor bicyc..
